Feature #2376
Updated by Junxiao Shi about 10 years ago
Command interest validation requires both signature verification and timestamp (as well as nonce) checking. There are several potential ways to handle signature verification (e.g., `ValidatorRegex` and `ValidatorConfig`), while there are also several potential ways to handle timestamp checking (e.g., send-and-stop, session-based control). A desired abstraction would be to separate the two functionalities apart. This feature implements For example, having a command interest validator that checks the which has a pointer to a Validator object as a member, and provide timestamp checking outside of a stop-and-wait [[CommandInterest]], while delegating signature verification to another inner validator. the normal Validator class.
